Adequacy of study:
key study
Study period:
2011-07-06 - 2011-07-07
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
according to guideline
EU Method A.2 (Boiling Temperature)
GLP compliance:
yes (incl. QA statement)
Type of method:
method according to Siwoloboff
Specific details on test material used for the study:
- Name of test material (as cited in study report): Jeffcat DPA
- Physical state: Liquid
- Lot/batch No.: PFW100241
- Other: Sample stored in cool well-ventilated area prior to testing
Key result
Atm. press.:
100.7 kPa
Decomp. temp.:
235 °C
Remarks on result:
not determinable because of methodological limitations

The sample began to change colour at 235°C. At 250°C, the sample had still not boiled.

The test substance starts to decompose at 235 °C. The measurements were taken at a pressure of 100.7 kPa.

Description of key information

In a GLP study according to test method EC A.2, the test substance was determined to decompose at above 235°C (Younis, 2011).

Key value for chemical safety assessment

Temperature of decomposition (state purity):
235 °C

Additional information

The substance was concluded to decompose before boiling.
